Installing Growatt Hybrid Inverters in Parallel | Parallel ARK Lithium Batteries With Battery Hub

In this episode of Billy's Workshop, we will be covering how to setup and install larger Growatt based off-grid solar setups. We will show you how to setup parallel Growatt inverters, as well as how to setup larger banks of Growatt ARK LiFePO4 Lithium-Ion battery systems. We will also go over how to configure parallel Growatt hybrid inverters with a Growatt Battery Hub.

Wow, that was way more in depth than I expected.

[@LisaPieri-uz2ti]

Great workshop Billy :)

[@lnostdal]

I was so confused by the Growatt documentation related to this. I understood that the inverters could be connected in parallel, but it seemed so pointless when the battery stack could only deliver 100A i.e. around 5kW of output power while discharging (and charging btw.). Nothing in the manual mentioned anything about hubs and multi-stacks - which IIRC break these limits. Thanks a bunch for the vid! :)

Glad this video helped! 🙌

[@lastcenturyclassics]

Well explained thanks 😁

[@dimitriosfilipakis4504]

hey brother.. just a quick question if you dont mind.. on the growatts parellel set up, specifically these same 5000 ES units, if one inverter faults/fails/abruptlyt shuts down, will the other continue to provide power? or stop as well?

[@garymeyer6419]

Thanks for the Video, busy with a DIY in South Africa doing parallel setup with x2 SPF5000ES units, as and when I get the parts, I will be using US3000C x4 with the Growatt RS485/CAN hub that's just arrived from the USA, this gives me hope that I am doing it right

[@GridFreeStore]

Glad we could help! All the best with your install 👊

[@jadoughanem568]

Much appreciated...

[@GridFreeStore]

Thanks!

Great video! Thanks! If I have 3 battery stacks with each 10 of them (total 25.6KWh each stack), does that mean I will need a much thicker positive and negative cables on the output side of the battery hub (or Growatt combiner hub) which can handle 300A? I assume maximum amps for each stack is 100A allowed, so combing all of 3 stacks will end up 48v and 300a if I'm not wrong?

[@GridFreeStore]

Heya, thanks for your question! Usually a multistack set up with a battery has multiple inverters. Each inverter will have its own cable pair to the bus and will only draw up to the maximum on one stack (depends on the specific inverter of course). If you have a no standard set up I.e. a single inverter that can draw 300A attached to a hub with 3 stacks, then yes, you will need to ensure adequate cable size and protections. You are welcome to contact us if you have any questions. E: [e-mail]

[@husseinsaleh73]

Thanks alot! Any tutorial on how the 2 outputs of the invertors are connected to the main for house loads

[@GridFreeStore]

We don't supply that information as in New Zealand that's prescribed electrical work (you're working with 240V) and must be done by an electrician.

[@EscribanoEl]

Unless I am mistaken (and I am happy to be corrected) whether you can do this or not depends on the inverters. It is very important that people realise that you cannot do this with the Growatt MIN series range of inverters. It would be helpful if Growatt made this clearer from the start in their publicity to avoid this confusion instead of emphasising the modular nature of their products.

[@GridFreeStore]

Yes, not every inverter is compatible - it can be quite confusing. That's why we only sell a few Growatt inverters and these batteries - we've tested them and know they work together.

[@SuperMghanem]

Great video but we are looking forward to watch more details while putting in function like how the power is distributed among the output and while charging from solar or grid how is it distributed or when some faults take places and so on

[@GridFreeStore]

Thanks for the feedback, will add it to the list of videos to make!

[@joostdewolde3956]

Hi, Thanks for this detailed video! It really helped me understanding the product. I've got 2 SPF 5000ES inverters in parallel and 8 ARK 2.5L-A1 batteries. I need an output of 10kW (200A x 51.2V), so I wanted to connect two groups of 4 batteries (each 100A) together with this ARK LV HUB-A1, but I noticed it's no longer in production. I live in the Netherlands and I can't get the hub here or anywhere else in Europe anymore unfortunately. Do you think it would be possible to combine the 2 BMS CAN communication cables together a different way, via a kind of different brand BMS combiner if that exists. Then I can connect the postives and negatives together with 2 bus bars myself. Or.. if you still have these hubs in stock, would it be possible to ship them to the Netherlands? Many thanks in advance! :)

[@GridFreeStore]

We do have these hubs in stock. Get in touch via our website, hopefully we might be able to sort something out for you! gridfree.store/

[@gwanga]

Great video. Thank you for this great explanation. This will really help a novice like me. Greetings from Brazil.

[@GridFreeStore]

Glad it helped! Let us know if you'd like anything else explained relating to solar and we'll make a video 😎

[@Itsalloutthere]

Do you know if the Growatt SPH 5000 TL BL-UP inverters can be connected in parallel? I want to get two of them but wanted to make sure it’s possible before I buy them. I can’t find any info in the manual!

[@GridFreeStore]

Unfortunately, we do not sell this unit so we cannot advise on this. Please get in touch with the store selling that unit to be sure. Check out our inverter range here: gridfree.store/collections/hybrid-inverters

[@neilwolstenholme6075]

is this effectively a growatt hub and two busbars in a box or does it contain some other logicplease? I ask because I gave been told that you cannot use a growatt hub and two busbars like this to share more than 10x ARK LV with 2 parallel spf5000 and this could be the solution to my problems

[@GridFreeStore]

They are 2 busbars plus a BMS communications combiner. You need these for multiple units/stacks. Each stack can have up to 10 batteries, so if you need more than this you will need to get a hub.

[@markusunterthiener2632]

which battery stack are you unsing ? want them :-) thxs alot

[@GridFreeStore]

The batteries in the video are the Growatt ARK 2.5L modular batteries. You can find more info on our product page: gridfree.store/products/growatt-ark-lifepo4-battery-2-56kwh
